Thank you Mrueschman. I will follow your suggestions.
Is there any result -report page for a patient whether he/she has apnea or not in SHHS files ? I need it to compare those with my analysis software result.
Thanks in advance
In addition, image and text does not match with the nssrid and edf files. Please refer to image. you can considershhs1-200001_filtered_data, shhs1-200002_filtered_data and shhs1-200003_filtered_data.
I am researching for an issue on apnea cases.
My question is: Is that possible to diagnose apnea basically from the SaO2- SpO2 values only ? By this, we will figure out if there are reasonable results and make people more comfortable to get apnea treatment from their houses, especially whom are disabled.
I use the polysomnography .edf raw values, filter Time-SaO2 with EDF browser and import to MS SQL.
In MS SQL I run a query code and calculate the oxygen desaturation during all time which is appoximately 8,5 hours for each, around 30.000 secs.
I focus on the AHI and RDI basically. As I know shortly, RDI = AHI + Arousals .
When I compare the real study results ( lets consider shhs1-200041_filtered_data ), non-apnea results generally match but existing-apnea results and my own results do not seem mathcing.
I wonder, is the approach has something to add, modify or change ? Can I get some reasonable and undestandable results with this methodology.
Beside, I can share the sql query code and results if anyone wants ?
I really appreciate to hear from experts as you.
